IMPROVEMENT IN SPRINGS FOR. RAILWAY CARS AND OTHER VEHICLES.

The Schedule referred to in these Letters Patent and making part of the same We, WILLIAM RHGDA NICHOLS and CHARLES WILLIAMS PIOKERING, of Philadelphia, county of Philadelphia, State'of Pennsylvania, have invented van Improvement in Springs for Railroad Cars and other Vehicles, of which the following is a specification.

Nature and Object of the Invention.

gether the ends of the two main plates of an elliptical spring such as is used for railroad cars and other vei hicles; and

Onr invention consists in combining with the peculiarly-bent ends of the said main plates at flanged or ribbed block or blocks and a pin, in the manner de-- scribcd hereafter, so that the said plates may be connected together at the ends effectually and economically. Description of the Accompanying Drawing.

Figure 1 is a side view of our elliptical spring, complete; I v Figure 2 is a perspective view of detached pieces illustrating our invention;

Figure 3, a transverse section of the end of the spring; and

Figures 4 and 5 show modifications of our invention.

General Description.

In figs. l and 2-. I A represents the end of the upper main plate, and

A, the end of the lower plate of an elliptical spring,

each end being bent to the semi-cylindrical form represented in the drawing, so that the two plates combined have a tubular termination, for the reception of the pin B.

A slot, to, is formed in this tubular termination of the combined plates, for the reception of the tubular block I), on each end of which is a rib or flange, b, so arranged that, when the block is fitted to. its place, one rib overlaps the bent ends x of both plates at one end of the slot a, the other rib overlapping the bent ends of both plates at the opposite end of the slot, the ribs being discontinued at d throughout a suflicient portion of their circumference to permit the insertion of the block into its place.

After the block has been adjusted to its proper position in the slot 0. of the plates, the pin B- is passed through the tubular termination of tb same, as well as through the block, and the ends of the pin are riveted, as shown .in fig. 3, or otherwise secured. The ends of the two plates are thus securely bound together by the ribs of the. block, while the latter 'is Ourinvent-ion relates to a mode of connecting topsarmanenfly and efle'ctmlny Egon-red by the riveted pin.

Independently of the eificacy of this mode of securing the ends of the plates together, it possesses the advantages ofsimplicity and economy, for the ends of the plates may be bent and cut in a suitable machine at one operation, while the blocks may be cast, so that no tedious fitting, demanding skilled, labor is required.

In the modification illustrated in fig. 4, two ribbed blocks or washers, D D, are used for embracing the opposite ends of the tubular termination of the two plates'Aand A of the spring.

In very large springs, two end blocks, as well as a central block, may be employed. r Fig. 5 shows a method of connecting the main plates when two or more springslare placed side by side. In this case, a ribbed block, D, is used between the springs and blocks or washers D at the ends, and the whole are bound together by-a single pin.

Y It will be evident that our'invention may be applied to the heaviest springsiequired for railroad cars, or to the lightest springs for other vehicles-to s'uch springs, for instance, as are composed of two plates only.
